Ventilation and extraction
A correct installation is important for correct operation of the appliance to ensure,
there is no build-up of heat at the back of the appliance. This heat must be allowed
to escape into the open air.
In the event of high ambient temperatures, full performance of the cooling unit
can only be achieved by means of adequate ventilation and extraction.
The unit is ventilated through
openings in the wall of the vehicle
(L 500). Fresh air enters at the
bottom and the warmed air flows
off through the upper ventilation
grille (flue effect).
The upper ventilation grille should
be positioned as high as possible
above condenser (K).
The lower ventilation grille should
be flush with the floor of the
vehicle, allowing any gas
leakages (heavier than air) to
escape directly into the open air.
Should this arrangement prove
impossible, a ventilation aperture
must be introduced by the manufacturer of
the vehicle into the recess floor intended for the unit's installation, in order to avoid the
accumulation, on this floor, of any non-combusted gas which might escape (according to
EN 1949). The ventilation grilles must have a free cross section of at least 400cm
2
.
This is reached using the Dometic Absorber Ventilation and Air Extraction
System L500 that has been tested and approved for this purpose.
Dometic ventilation systems include installing frame, vent grille and winter cover.
The oven’s ventilation and exhaust extraction is realised with roof mounted flue outlet
only (Truma- roof flue outlet).

Correct mounting of the lower ventilation grille facilitates the access
to the electrical and gas connections during maintenance work.
